postfix - alias database uses openldap. Kerberos authenticat

[mxc]

Hi there,

I have set up postix to use ldap as the source for aliases in the main.cf file. Unfortunatley this means postifx needs to login to the ldapserver to do this. My ldap server uses kerberos authentication. Is there a way to setup postifx to login via kerberos?

I have tried added the following principle " add -r postix@host/realm" via kadmin and exported the key to the keytab file on the machine where postifx is running.

This doesnt appear to have worked. I am using heimdal.

thanks
